I was thinking of involving my 6 and 7 yr old in hatching some eggs. I did it in a school when I was in 4th grade and it was a very nice experience. We have 12 hens so I do not want it to be a new career for me even thou I hear that it is addictive. I just want to hatch a few to add to our flock. Does anyone have a recomendation for an incubator that will work for a decent price. I do not want the kids to be disapointed.
